[ASN.1] Regarding the BER encoding of choice types within MAP GSM Specs.

[Sriraman, Santhosh Kumar]

Hi, 



How will i encode the sample sequence(appears in GSM specifications) below
using basic encoding rules?. 


Sequence {
value0 [0]  NULL , 
value1 [1]  INTEGER,
value2 [2]  CHOICE {
             flag   [0] BOOLEAN,
             value [1] INTEGER}
}
 
According to BER rules , there are no additional TL wrappers for choices. 
The decoding is just that of the chosen item. 

can i put additional TL Wrapper for the 'value2'? Is that a legal BER
encoding?

Waiting for your answer!
